Function Documentation

VMEXPORT jint vm_attach	(	JavaVM *	java_vm,
		JNIEnv **	p_jni_env
	)

Registrates current thread in VM, so it could execute Java.

Parameters:

[in]	java_vm	- current thread will be attached to the specified VM
[out]	p_jni_env	- will point to JNI environment assocciated with the thread

VMEXPORT jint vm_detach

(

jobject

java_thread

)

Frees java related resources before thread exit.

VMEXPORT void jthread_set_tm_data	(	jobject	thread,
		void *	data_ptr
	)

Stores a pointer to TM-specific data in the java.lang.Thread object.

A typical implementation may store a pointer within a private non-static field of Thread.

Parameters:

[in]	thread	- a java.lang.Thread object those private field is going to be used for data storage
[in]	data_ptr	- a pointer to data to be stored

VMEXPORT void* jthread_get_tm_data

(

jobject

thread

)

Retrieves TM-specific data from the java.lang.Thread object.

Parameters:

[in]

thread

- a thread

Returns:

TM-specific data previously stored, or NULL, if there are none.

VMEXPORT int vm_objects_are_equal	(	jobject	obj1,
		jobject	obj2
	)

vm_objects_are_equal
obj1 jobject
obj2 jobject

Returns:

int

hy_inline vm_thread_t jthread_self_vm_thread

(

)

Gets VM_thread from native thread.

hy_inline vm_thread_t jthread_get_vm_thread

(

hythread_t

native

)

Gets VM_thread from a given native thread.

hy_inline vm_thread_t jthread_self_vm_thread_unsafe

(

)

Gets unsafe VM_thread from native thread.

VM_thread could be not initialized.

hy_inline vm_thread_t jthread_get_vm_thread_unsafe

(

hythread_t

native

)

Gets unsafe VM_thread from a given native thread.

VM_thread could be not initialized.

hy_inline hythread_t jthread_get_native_thread

(

jobject

java_thread

)

Gets native thread associated with a given Java thread.

Returns:

native thread

hy_inline vm_thread_t jthread_get_vm_thread_from_java

(

jobject

java_thread

)

Gets VM_thread associated with a given Java thread.

Returns:

pointer to VM_thread or NULL
